The Late Jurassic (or Malm) Epoch of the Jurassic Period is the unit of geologic time from 161.2 ± 4.0 to 145.5 ± 4.0 million years ago, which is preserved in Upper Jurassic strata.
Subdivisions
Edit
The Late Jurassic is divided into three ages, which correspond with the three (faunal) stages of Upper Jurassic rock:
| Tithonian | (150.8 ± 4.0 – 145.5 ± 4.0 Ma) |
| Kimmeridgian | (155.7 ± 4.0 – 150.8 ± 4.0 Ma) |
| Oxfordian | (161.2 ± 4.0 – 155.7 ± 4.0 Ma) |
PaleogeographyEdit
Pangaea broke up into two supercontinents, Laurasia to the north, and Gondwana to the south. The result of this break-up was the spawning of the Atlantic Ocean. However, at this time, the Atlantic Ocean was relatively narrow.
